1. Anodizing: it can form a porous oxide film with a hardness of up to 500 HV; the oxide film with a porous structure can also absorb lubricants and pigments to enhance the corrosion resistance and wear resistance of the surface of the material; Insulation effect, can prevent breakdown voltage greater than 30V / μm; strong high temperature resistance, can withstand high temperature of 1500 ℃; use good adsorption capacity can be oxidized and colored into various decorative colors, widely used in aerospace, electronic appliances, Construction of various aluminum profiles and building decoration. 2. Electrophoretic coating: water is used as the dispersion medium, and the amount of co-solvent is small, which reduces the pollution of air and water, and there is no danger of fire; the paint has good swimming permeability and can cover the edges and gaps of aluminum profiles. Forms a dense and uniform oxide film, and the overall anti-corrosion ability is very strong; the appearance quality is high, no sagging phenomenon occurs, and no solvent is condensed on the surface of the profile to form a poor appearance; the advanced RO circulation system is adopted, so that the coating recovery rate is 98% More than%, waste water discharge is small, which not only saves chemical coatings, but also reduces environmental pollution. 3. Powder coating: The molecular weight of the resin used in powder coating is larger than that of solution-type coating, which makes the surface of the aluminum profile have good chemical resistance. The powder coating can obtain a coating of 50-300μm, which greatly reduces the number of painting It saves working time, there is no droop phenomenon and pinhole defects caused by solution-type coatings during coating, and it is possible to obtain better film layers to make aluminum profiles sturdy and durable; the colors are colorful and the decorative effect is improved; for aluminum The quality of the surface of the substrate and the quality of the pretreatment are not as strict as the first two treatment methods.

Defect characteristics of surface cracks on aluminum profiles: The surface of aluminum profiles exhibits longitudinal, fish-like, repetitive, intermittent breaks, which are severely disconnected. Causes of surface cracks in aluminum profiles: (1) The extrusion coefficient of aluminum profile is too large, the extrusion temperature is too high (rod, barrel, die three temperature), and the extrusion speed is too fast; (2) The squeezing force is unstable, suddenly high or low, or the speed difference between multiple speeds is obvious, and the speed change is sudden when shifting; (3) When the aluminum alloy profile is extruded, the head end presses (presses) too fast, the tail end runs or does not decelerate, and a large amount of aluminum penetrates into the dead zone; (4) The quality of the rod is poor, the rod is overburned, large grains, and loose. Pressure surplus (V3 aluminum) is too thin; (5) The design and manufacturing of the extrusion mold with a severe flow velocity ratio is unreasonable. Elimination of surface cracks on aluminum profiles: (1) Profiles with excessive extrusion coefficients can be produced on a small machine with an appropriate extrusion ratio; in addition, the extrusion temperature must be controlled strictly according to the production process requirements and an appropriate extrusion speed must be used; (2) The operator is concentrated, the speed is stable, the pressure cannot be high or low, and the manual operation is coordinated when changing gears; (3) The front and rear ends of the aluminum profile stoppage are dead zones or V3 volume (aluminum rod surface) aluminum, which has many impurities, poor quality, and insufficient viscosity, so the extrusion speed of the head and tail of the profile should be slowed down; (4) The surface of the aluminum rod should be fine and clean without oil stains, the internal organization must meet the standards, and the pressure surplus should remain normally (5% of the rod length); (5) The designer of the extrusion die shall design and manufacture a qualified die with uniform flow velocity.

Ministry of Industry and Information Technology: The aluminum industry standard conditions will be released as soon as possible to promote the orderly development of the industry Recently, the Ministry of Industry and Information Technology replied to the No. 7157 of the Second Session of the 13th National People's Congress, stating that the "Aluminum Industry Standard Conditions" will be released as soon as possible to promote the orderly development of the industry; and the relevant departments will further consolidate the elimination of backward production capacity departments to promote the working mechanism and rule of law. Long-term mechanism, continue to carry out special energy-saving supervision on the implementation of energy-saving limit standards in the aluminum industry, implement the requirements of the “Guidance Opinions”, increase the elimination of outdated process equipment, and promote the orderly exit of uncompetitive production capacity. The original is as follows: I. Suggestions on strictly controlling the total amount and limiting the incremental development of alumina The alumina industry is an important part of the aluminum industry. In recent years, China's alumina industry has developed rapidly. In 2018, the production capacity exceeded 80 million tons, and the output reached 72.53 million tons, which basically met the domestic electrolytic aluminum production needs. At present, domestic electrolytic aluminum has implemented a strict control of the total capacity policy, and the overall demand for the alumina market is limited. In the case of increased constraints on resource supply and environmental capacity, it is not appropriate to control the total alumina production capacity and capacity. Administrative measures such as reduction or equal replacement will constrain the development of the industry. In accordance with the principles of marketization and rule of law, a fair market environment should be created to guide the orderly and healthy development of the alumina industry. In 2018, the Development and Reform Commission and the Ministry of China issued the "Notice on Promoting the Orderly Development of the Alumina Industry" (Development and Reform Office Industry [2018] No. 1655, hereinafter referred to as the "Notice"), from strengthening scientific planning, strict project management, and speeding up The transformation and upgrading, implementation of the main responsibility, and strengthening of publicity and guidance have made clear requirements for regulating the development of the alumina industry. In the next step, we will continue to adopt market-oriented and rule-of-law methods, continue to strictly implement the relevant laws and regulations on land, environmental protection, energy consumption, quality, safety, etc., so that the market plays a decisive role in resource allocation, and timely construction of alumina projects Various forms such as letters, surveys, and spot checks are conducted to ensur...
